首先对以下内容进行介绍:
(1)多媒体广播多播业务(Multimedia Broadcast and Multicast Service,MBMS)或广播多播业务(Multicast Broadcast Service, MBS);
在通信系统中,可以通过以下两种方式发送:
MBMS/MBS发送方式1:通过在MBMS单频网(Multimedia Broadcast multicast service Single Frequency Network,MBSFN)子帧中通过物理多播信道(Physical Multicast Channel,PMCH)物理信道发送。其中,控制信息通过系统信息(如,SIB13)和广播控制信道(Multicast Control Channel,MCCH)发送,数据通过广播业务信道(Multicast Traffic Channel,MTCH)发送。
MBMS/MBS发送方式2:通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度的物理下行控制信道(Physical Downlink Shared Channel,PDSCH)信道发送。其中,控制信息通过系统信息(如,SIB20)和单小区广播控制信道(Single Cell Multicast Control Channel,SC-MCCH)发送,数据通过单小区广播业务信道(Single Cell Multicast Traffic Channel,SC-MTCH)发送。其中,SC-MCCH通过单小区无线网络临时标识(Single Cell RNTI-Radio Network Temporary Identity,SC-RNTI)PDCCH调度的PDSCH发送,SC-MTCH通过G-RNTI PDCCH调度的PDSCH发送。
(2)NR MBS业务在N3接口的提供方式;
5GC单个MBS业务交付:5G CN接收MBS数据分组的单个副本,并通过每个UE分组数据单元(packet data unit,PDU)会话将这些MBS数据分组的单独副本交付给各个UE,因此对于每个这样的UE,需要一个PDU会话与多播会话相关联。
在这种方式下,用户面功能为传统的用户平面功能(User Plane Function,UPF);但实际上UPF也是从MB-UPF获得多播的数据5G CN接收MBS数据分组的单个副本,并经由每个UE PDU会话将那些MBS数据分组的单独副本传递给各个UE,因此对于每个这样的UE,需要一个PDU会话与多播会话相关联。
5GC共享MBS流量交付:5G CN接收MBS数据包的单个副本,并将这些MBS数据包的单个副本交付给无线接入网(Radio Access Network,RAN)节点。
在这种方式下,用户面功能为增强的MB-UPF;5G CN接收MBS数据包的单个副本,并将这些MBS数据包的单个副本传送到RAN节点。
MB-SMF向MB-UPF提供转发规则(forwarding rule),MB-UPF根据这个转发规则来发送MBS的数据给相应的基站或者UPF。
下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的资源释放方法及装置进行详细地说明。
图2是本申请实施例提供的资源释放方法的流程示意图之一,如图2所示,该方法由第一网络节点执行,该方法包括如下步骤:

在通信系统中,对于组播(multicast)业务,可能只有无线资源控制(Radio Resource Control,RRC)连接(CONNECTED)状态的UE可以接收组播业务,且基站可以严格知道有多少RRC-CONNECTED的UE在接收组播数据。
然而当基站发现没有UE在接收multicast业务时,基站可以向核心网指示N3资源的释放和/或直接停止multicast业务的发送,从而提高资 源的使用率。
